Are we starting to see tech companies worried about how stable their userbase is instead of how much they can grow and get attention from people? In a time of growth every bit of extra activity is great. If you run hot and burn out someone, but attract ten users in the process, great! But if growth is slow and you are shifting gears to keeping users around, having a time based feed is more sustainable? I'm just guessing here, but I wonder why Facebook is making this after so many years of people asking for it. They just backtracked on Facebook accounts for Oculus as well.
